Hi everyone. Suddenly when I start a flight with any aircraft my speaker produce a summing sound which is stronger than game sound. It happens when starting a flight. Nothing has been changed except a new m2 SSD cooler. Have desinstalled cooler with m2 and reset video card that might have created static. No solution. All sounds are from motherboard Realtek and settings have not been changed. Any ideas?
The humming may have something to do with: a) the cable connector on the back of the pc or speakers not being connected all the way, or b) any related power connection being askew. Does this happen with other sources? Does this happen with a pair of headphones connected to the case’s headphone jack? You might want to try connecting the speakers to the headphone jack just to check. --Redeye
Thanks for your reply.
It does not happen with other sims or sources as music. With headphones it is less noticeable but the speakers still emit the humming especially the Bass settings. Disabling Bass the humming is weaker but with higher pitched tone . Disabling High Definition Audio Device in Device manager there is strong humming with Headset. But if I have the sound settings to the headset I can still hear strangely from the SPEAKERS if the speakers are not disabled. All cables are well set and audio drivers up to date.
When launching the game and the aircraft show up there the humming starts (ready to Fly button not pressed) . Also I noticed that starting the game the audio interrupts several times until sim is loaded. Thus with headset or wwithout headsed it is the same! Therefore I think it is a MSFS issue not hardware
Note:Forgot to tell you that if I connect the Headphone to an usb sound card there is no humming!
Sounds like you have a bad amplifier in your powered speakers. Probably some capacitors have gone bad. OR there is something in your room that is creating RF (radio frequencies) and the amplifier is picking it up and “amplifying” it. Things like cheap light dimmers or badly designed switching power supplies can put off RF that are picked up by your amplified speakers. Best of luck in troubleshooting the problem. Start by taking the amplified speakers to a different room and see if the hum disappears.
Thanks for your reply. To check what you said I connected an older speaker system with subwoofer and it shows the same problem especially if basses are high. So it is a MSFS2020 issue not a sound hardware, unless the motherboard audio has problems… but I think this is not the case as any other game functions well in audio. Have also uninstalled msfs2020 and installed it the quick way s described in youtube: MSFS2020 Install in seconds: https://www.youtube-nocookie.com/embed/S4wbHxPhGvU But this did not help.
This is a very odd issue.
I see this posted in another thread, it may be some help.

Hi, thanks for your opinion. Have already seen the link you posted. I had no issues before, this problem appeared suddenly and it is with both speaker settings the new and old one

Do you have (or have you tried this with) low power mode on?
Sorry do not know what low power mode on is
Ok, thanks I think this resolved it. There is still humming but much less. I have also updated the last Windows update, maybe this helped too. Anyway thanks very much for your help. Can you tell me what else this setting changes and for what it is, does it degrade anything?
Sorry for the very late reply, I just noticed this today.
It prevents some of the start up displays from running, thus saving power.
It does not affect the running of the sim.
